Ancient Through Pre-Industrial Times Unhygienic living conditions and little access to effective medical care meant life expectancy was likely limited to about 35 years of age. Broader than the narrow metric of the infant and child mortality, which focus solely at mortality at a young age, life expectancy captures the mortality along the entire life course. But just how common was it? Data on GDP per capita is taken from Bolt, J. and J. L. van Zanden (2013). No country in the world has a lower life expectancy than the countries with the highest life expectancy in 1800. The divided world of 1950 has been narrowing. Among them he lists the consul M Valerius Corvinos (100 years), Ciceros wife Terentia (103), a woman named Clodia (115 and who had 15 children along the way), and the actress Lucceia who performed on stage at 100 years old. Why do women live longer than men? The following graph is an updated version of the graph in the paper Broken Limits to Life Expectancy published in Science byOeppen and Vaupel in 2002.10. Thats life expectancy at birth, a figure dramatically influenced by infant mortalitypegged at the time as high as 30%.

The average person can expect to live a longer life than in the past, irrespective of what age they are. To ensure that the resulting estimates of the probabilities of death within each age interval are smooth across the lifetime, it is common to use mathematical formulas, to model how the force of mortality changes within and across age intervals. Archaeologists Christine Cave and Marc Oxenham of Australian National University have recently found the same. For example, the UN estimates that the (period) global life expectancy at age 15 in 2005 was 73.6 years.

The few European countries with a life expectancy close to 40 years have more accurate data for this time period so that it seems unlikely that the life expectancy there was over 40 years, or at best it was only barely over 40 years. However, this can be broken down further into healthy life expectancy and years lived with disability. The average age of death was 30, and that wasnt a mere statistical quirk: a high number of the skeletons were around that age.

The rise best visible on the Map-view shows that the increasing life expectancy is not only due to declining child mortality, but that mortality rates at higher ages also declined globally. The First Update of the Maddison Project; Re-Estimating Growth Before 1820. A metal roof's lifespan is estimated to be between 40 to 70 years, depending on the type of metal used. Those records show that child mortality remained high. (The authors speculate that the prevalence of dangerous lead plumbing may have led to this apparent shortening of life).
